Quoted from RandyW:I keep all of my machines on coin play. Half the fun of Pinball is playing to win a credit. And for arcades, they instantly become useless if I have unlimited credits. In home use, you will likely never put enough quarters through your game to cause any noticeable wear on the door.
But aren’t you worried about the wear and tear on your coin mechs? And perhaps wearing off a little of the paint around the coin slots. You bought these machines to have fun. How dare you!!
